I was reading about an ambulance service in England that was getting called out, up to 80 times a day just for women who needed assistance with complications due to morning sickness- they stated that the doctors were not dealing with the morning sickness concerns, which resulted in a need for an ambulance due to dehydration and other complications.
It's very important to have a doctor in your corner that listens to you- do you feel like you have that? Would you consider switching because you don't feel like they are listening?
